I. The ruin of Judah and Jerusalem is here pronounced. The decree has gone forth, and shall not be recalled. 1. God here asserts his own sovereignty and power (v. 27): Behold, I am Jehovah, a self-existent self-sufficient being; I am that I am; I am the God of all flesh, that is, of all mankind, here called flesh because weak and unable to contend with God (Ps. lvi. 4), and because wicked and corrupt and unapt to comply with God. God is the Creator of all, and makes what use he pleases of all. He that is the God of Israel is the God of all flesh and of the spirits of all flesh, and, if Israel were cast off, could raise up a people to his name out of some other nation. If he be the God of all flesh, he may well ask, Is any thing too hard for me? What cannot he do from whom all the powers of men are derived, on whom they depend, and by whom all their actions are directed and governed? Whatever he designs to do, whether in wrath or in mercy, nothing can hinder him nor defeat his designs. 2. He abides by that he had often said of the destruction of Jerusalem by the king of Babylon (v. 28): I will give this city into his hand, now that he is grasping at it, and he shall take it and make a prey of it, v. 29. The Chaldeans shall come and set fire to it, shall burn it and all the houses in it, God's house not excepted, nor the king's neither. 3. He assigns the reason for these severe proceedings against the city that had been so much in his favour. It is sin, it is that and nothing else, that ruins it. (1.) They were impudent and daring in sin. They offered incense to Baal, not in corners, as men ashamed or afraid of being discovered, but upon the tops of their houses (v. 29), in defiance of God's justice. (2.) They designed an affront to God herein. They did it to provoke me to anger, v. 29. They have only provoked me to anger with the works of their hands, v. 30. They could not promise themselves any pleasure, profit, or honour out of it, but did it on purpose to offend God. And again (v. 32), All the evil which they have done was to provoke me to anger. They knew he was a jealous God in the matters of his worship, and there they resolved to try his jealousy and dare him to his face. "Jerusalem has been to me a provocation of my anger and fury," v. 31. Their conduct in every thing was provoking. (3.) They began betimes, and had continued all along provoking to God: "They have done evil before me from their youth, ever since they were first formed into a people (v. 30), witness their murmurings and rebellions in the wilderness." And as for Jerusalem, though it was the holy city, it has been a provocation to the holy God from the day that they built it, even to this day, v. 31. O what reason have we to lament the little honour God has from this world, and the great dishonour that is done him, when even in Judah, where he is known and his name is great, and in Salem where his tabernacle is, there was always that found that was a provocation to him! (4.) All orders and degrees of men contributed to the common guilt, and therefore were justly involved in the common ruin. Not only the children of Israel, that had revolted from the temple, but the children of Judah too, that still adhered to it—not only the common people, the men of Judah and inhabitants of Jerusalem, but those that should have reproved and restrained sin in others were themselves ringleaders in it, their kings and princes, their priests and prophets. (5.) God had again and again called them to repentance, but they turned a deaf ear to his calls, and rudely turned their back on him that called them, though he was their master, to whom they were bound in duty, and their benefactor, to whom they were bound in gratitude and interest, v. 33. "I taught them better manners, with as much care as ever any tender parent taught a child, rising up early, in teaching them, studying to adapt the teaching to their capacities, taking them betimes, when they might have been most pliable, but all in vain; they turned not the face to me, would not so much as look upon me, nay, they turned the back upon me," an expression of the highest contempt. As he called them, like froward children, so they went from him, Hos. xi. 2. They have not hearkened to receive instruction; they regarded not a word that was said to them, though it was designed for their own good. (6.) There was in their idolatries an impious contempt of God; for (v. 34) they set their abominations (their idols, which they knew to be in the highest degree abominable to God) in the house which is called by my name, to defile it. They had their idols not only in their high places and groves, but even in God's temple. (7.) They were guilty of the most unnatural cruelty to their own children; for they sacrificed them to Moloch, v. 35. Thus because they liked not to retain God in their knowledge, but changed his glory into shame, they were justly given up to vile affections and stripped of natural ones, and their glory was turned into shame. And, (8.) What was the consequence of all this? [1.] They caused Judah to sin, v. 35. The whole country was infected with the contagious idolatries and iniquities of Jerusalem. [2.] They brought ruin upon themselves. It was as if they had done it on purpose that God should remove them from before his face (v. 31); they would throw themselves out of his favour.
